The AP331A is a precision voltage comparators with an offset
voltage specification as low as 8.0 mV max for comparator which
were designed specifically to operate from a single power supply
over a wide range of voltages. Operation from split power
supplies is also possible and the low power supply current drain
is independent of the magnitude of the power supply voltage. The
comparator also have a unique characteristic in that the input
common-mode voltage range includes ground, even though
operated from a single power supply voltage.
Application areas include limit comparators, simple analog to
digital converters; pulse, square wave and time delay generators;
wide range VCO; MOS clock timers; multivibrators and high
voltage digital logic gates. The AP331A is designed to directly
interface with TTL and CMOS. When operated from both plus
and minus power supplies, the AP331A will directly interface with
MOS logic where their low power drain is a distinct advantage
over standard comparators.
